N.B.: Sorry i don't want to stress you out, i know it's hard being a
developer. Especially when the software is this complex :)
I am kind of in a pinch here, having to solve a lot of complex
expressions - and it seems i can't rely on sage's solver not
mistreating symbols as reals :/

I am not sure if this is even related. Does the solver rely on maxima,
too!?
The following should yield at least one complex solution... (See also
at the end of https://sage.q1cc.net/home/pub/1/ )
a,b = var("a,b")
solve([a*b==1,a+b==0],a)
[]
solve([a*b==1,b==-a],a)
[]
solve([a*(-a)==1],a) # Now
Add: I found this:

a bug
report.
If this is actually a bug i will open a ticket.
I published a demo sheet at: https://sage.q1cc.net/home/pub/1/
Thanks in advance,
